The booze room

My colleague Ernst had his birthday last Monday and now there was delayed cake.

In the evening we visited another school for Milan. I liked it very much, I actually think it's my favourite but it's also the one furthest away so it's probably not gonna be the one...

There was a room with this sign above it. I have no idea what the room was for but it had my name on it and pictures of booze so I figure it must be something good, no? :-)
